Regular perturbation is applied to the Manakov equation and motivates a generalized correlated phase-and-additive noise model for wavelength-division multiplexing over dual-polarization optical fiber channels. The model includes three hidden Gauss-Markov processes: phase noise, polarization rotation, and additive noise. Particle filtering is used to compute lower bounds on the capacity of multi-carrier communication with frequency-dependent powers and delays. A gain of 0.17 bits/s/Hz/pol in spectral efficiency or 0.8 dB in power efficiency is achieved with respect to existing models at their peak data rate. Frequency-dependent delays also increase the spectral efficiency of single-polarization channels.

降低双极化光纤通道容量的不匹配模型

规则扰动应用于 Manakov 方程，并为双偏振光纤通道上的波分复用提供了广义的相关相位和加性噪声模型。该模型包括三个隐藏的高斯-马尔可夫过程：相位噪声、偏振旋转和加性噪声。粒子滤波用于计算具有频率相关功率和延迟的多载波通信容量的下限。相对于现有模型的峰值数据速率，实现了 0.17 位/秒/Hz/pol 的频谱效率增益或 0.8 dB 的功率效率增益。频率相关延迟还增加了单极化信道的频谱效率。
